To all whomz't may concern:

Be it known thatwe, HENRY C. SCHU- MAGHER and WILLIAM A.; WINTnRs, both` citizens of the `United States, and residents of Barberton, in the county of Summit and State ofl Ohio, have invented certain new and useful lmprovements in `Machines for Making Match-BOX Shucks, of which the followingis'a specification.

rThis invention relates to machines for malrilngmatch-box' shucks comprising each a" 'stripof thin veneer bent into appropriate formV having its ends overlapped to constitute one of the narrow longitudinal sides of the shuck, and comprising also a thin ,coveru ing of paper Ywhich is gluedor pasted to the tubular body. ln said machinesthe veneer body ofthe shuck is formed on .a suitable n mandrel or forming bar,` rectangular incrosssection, and the paper cover, .withor without printed matter thereon, is then :wrapped about and affixed to such body. i

The present inventionjis in the nature of an attachment for shuck machines of the type mentioned; .and its object isto provide simple and efficient means whereby; in the fproduction of= thel shucl;` the proper v crosssectional -forrn Vof the yveneer body is maintained and A.the kpaper cover is uniformly applied thereto; thus insuring afproduct having the requisite structural form, size and appearance.

`To this end f the invention generally stated-comprises means whereby the folded veneer body is accurately positioned oni the mandrel or `forming bar and whereby the paper-cover and the said body are firmly held iin close Contact vduring the final fold-` ing ofthecoveriiaps.

rf-he :invention also comprises .showing a veneer .body with its partially folded cover on `the mandrel or forming bar; and indicating in dotted lines theactive position of the top pressure member and also thepath of the folding memk. i Yand therefore a preferred form of folderxis `various feahereinillustrated. This folder comprises a :tures of constructionyand combinations of MACHINE Forv MAKING MATCH-BOX sHUCKs.

ber in respect to the Vprojecting ends of the partially `folded cover. i y

'F ig. 3 is a perspective view, enlarged, of said body and its partially folded cover, howing a: portion of the mandrel in dotted mes. i n

.Figs ,4,5 and 6. aretransverse sections through the mandrel showing the pressure membersin active relation to the partially `formed shucl, and showing also the final of veneer of prescribed size is folded upon the mandrel to produce a body or skillet7 'paper-covered veneer are formed` by any usual or approved type of snuck making machine; that is to say, a rectangular sheet comprising a top una bottom b and two narrow longitudinal sides c, c respectively, whereof the side c is formed `by the overlapping wof the end portions of the material;

`and a sheet of thinpaper d of propersize,

vhavingpa-ste applied to itsunder surface,

is vthenclosely wrapped upon and affixedto the veneer body thus `produced, the final folding of the paper being eected by over? ,lapping its ends and pasting them together and to. the narrow side c ofthe veneer body.

The `mechanism embodyingour invention is associated with the means for aecomplishingthe final folding of the `paper cover,

horizontal .bar 11 whichfis'so f mounted and .operated in relation to the adj'acentside of the ,mandrel as -to foldin successive order .against the veneer body the upper and lower projecting ends iaps CZMZ, respectivelyof the paper cover. 'In thepresent instancethe -folder bar ll'is supported on the upperend of an upstanding arm 12 which is pivotedat its lower extremity to `the free' end of a lever 13 which, in turn, is fulcrumed on a` shaft 14 having its bearings'in an `upright nected bymeans of a linkfl with a wristj pin `17' on a cam 18 which isfast on a l 1 5 on the bed plate. 'lhe `lever 13 is conshaftY 19 ofl the machine, whereby the said*r lever and its attached folder bearing arm 12 -are vertically actuated. The arm 12 is .held in contact with the cam 1S by means of a retracting spring 2O which 'is secured n tov said arm and to an. adjustable screw member 21 on the upright 15; the contour of the cam being such as to 'effect conjointly with the spring, horizontal movement of the folder bearing arm'.V The resultant of the described vertical and lhorizontal movements of 'the folder bearing arm is'an approximate figure 8 movement of the folder arm as indicated by the' dotted lines in Fig.

2 atthe right of the mandrel; that is to say, the bar' 11 'swings inward Vand upward toward the adjacent side ofthe mandrel so as to vimvpinge against the lower projecting end flap i d2 of the' paper r cover and press it kfirmly toward and againstthe veneer body, as indicated' in Fig. 4; then outward and upward above the upper projecting end flap d of the c'over, asindicated in Fig. 5, and then downward and inward toward the mandrel as indicated in' Fig. 6 so asto press such latter end flap against' the veneer bodyV and kthe contiguous cover fold; thence returning to its originalposition. as shown in Fig. 2.

According to one vfeature j ofl our vinvention we provide in close parallel relation to that side" of the-mandrelcontiguous to the overlapping side portions 0 of 'the shuck body,a horizontal pressure' bar 22 which bears yieldingly against' such side portions during lthe `travel ofthe vvshuckalong the mandrel vtoward the final folderv for thepa per cover; 'thereby insuring the re-closing vof such Overlapping portions'in the event of their springing outward from theman- I of the bar is splayed to permit the ready passage' of the lapsj of the shuck bodyv be- I'tween the mandrel and 'the bar.` v i Another feature Yof 'our f invention coniprisespressure means/constructed and operated to `app'lyftotheftopfof the cover, be-

forethe final Afoldingnof ther projecting end flaps` thereof, al` yielding drawing action toward the folding mechanism, such action tending not only yto stretchfthe paper cover 'and eliminate excess paste therefrom, but also toremove-from the cover any buckle or wrinkle therein due t0 the opening and subsequent closing voffthe 'laps'of v.the shuck body. Thisbody V'with the partially folded .cover thereon is thusl firmly held against the top andside of the mandrel, with the projecting end iaps of the cover in position to be efficiently acted upon by the folder bar 11 above-described. 'In the preferred form of our invention herein illustrated the top'pressure means includes a foot comprising a metal plate 29 having an under surface of rubber 30 or other appropriate frictional substance. This pressure foot is secured to the free end of a spring arm 81 which is borne by the upper end of the upstanding arm'32 of a bell-crank lever fulcrumed on a stud .on the upright 15. The other arm of the leveioverhangs 'a cam 34 on the shaft L19 yand is maintained in 'contact therewith by a retracting spring 35 which couples the arm 33 to an underlying rocker arm 36 pivotallyV supported on the shaft 14. The arm 36 extends beneath 'the cam Saand is maintai'ned in contact therewith by the action of the spring. The position of the pressure foot relatively to the fulcrum of the bellcrank lever is such that when the lever arm 33 is partially `lowered the pressure foot impinges against the -top of the shuck cover, and the contour of the cam 34l is such that in one part of its rotation it permits such partial lowering of the pressure foot, and then acts upon and forcibly depresses the underlying rocker arm 36 in such ka manner as to augment the tension of the spring` and cause the pressure foot to exert additional yielding pressure upon the shuck cover, which pressure, by virtue of the Iiexible mounting of the foot, effects a motion of the foot transversely of the mandrel and toward the folding mechanism with the result above mentioned. `By the arrangement of cam, spring and lever mechanism just described the' pressure foot is positively raised by the vaction of the cam 34- on the klever arm 83 and 'is yieldingly lowered and transversely moved through the action of the cam on the spring-connected rocker arm 36.

The relative timing of the pressure foot and the folder operating mechanisms is such that while the foot is acting on the paper cover, the' folder bar 11 is movingupwardly Ain contact with the' lower iiap 'of the cover.

Preferably the lever arm 31 is provided with asuitably-disposed set screw 37 which bears upon the springarm and affords a ready means whereby said arm may be vertically adjusted within limits in respect to' the mandrel in order to vary the pressure'of the f foot on the shuck cover, as need may require.

It' is to be understood that our'invention is 'not limited to the specific details of construction herein shown and described, as the mechanism may be modified without departing from the principle of the invention delined in the appended claims.

We claim- 1. The combination with the mandrel and the final cover-folding mechanism of a machine for making paper-covered veneer shuclrs, of a friction member movable upon and from the top fold of the cover, a spring arm supporting said member, a lever for supporting said arm, and means for positively raising and yieldingly lowering the said lever, whereby the said friction member is caused to exert a transverse drawing action on the cover, said means including a spring and connections whereby the tension of the spring is augumented during the lowering of the said lever.

' 2. The combination with the mandrel and the final cover-folding mechanism of a machine for making paper-covered veneer shuclrs, of a friction member movable upon and from the top fold of the cover, a spring element supporting said member, a bell crank lever to one arm of which said element is attached, a rock arm below the other l arm of the lever, a spring coupling the said roclr arm and the adjacent lever arm, and a cam mounted to act upon the coupled arms in opposition to the force of the spring.
